Photographer’s Note

The coastal area near Trapani came to be exploited back in the time of the Phoenicians who, realizing the extremely favourable conditions available, set about building basins in which to collect salt: this valuable commodity they then exported all over the Mediterranean.

So this otherwise barren stretch of land came to be systematically worked: from the shallow water, the searing temperatures and arid winds (which also facilitates evaporation, of course) was born a tough, but beneficial industry to produce the precious element, so vital to the survival of man.

One of the foremost and fundamental properties of salt is its ability to preserve food, a quality with which the earliest peoples were familiar, using it to treat perishables for the lean winter months or simply during transportation.

After the Phoenicians, however, there are no reliable references to the salt pans around Trapani until the Norman era when Her Majesty the Emperor Frederick Il himself alludes to them in the Constitutions of Menfi, making them a crown monopoly. From this date on, the rise in status of the port of Trapani may be tracked fairly easily.

The economic success of the saltpans, meanwhile, show that major fluctuations in output shadowed the rise and fall in fortunes of the territory as it succumbed to various external events beyond its control. War, epidemic, transitions of government from one dominion to another influenced the production and trading of salt just as it would any other field.

On the whole, the area was profitable, as was the commercial activity itself, and that is why it has continued, albeit with fits and starts, until the present day.

Large, slow windmills are used as the energy source in the completely environment-safe work cycle of salt harvesting, not so much a concession to modern-time concerns, as simply the way things have always been done on these salt pans.

It's possible to stroll along the magical "Via del Sale" with its imposing mountains of rock salt rising up against the background of the azure sea, visiting a few active saline and their characteristic windmills.

The windmill comprises a conical building, capped with a conical roof, and six trapezoid vanes consisting of cloth sails attached to wooden frames that catch the wind and propel a system of mechanical gears. Inside the building, a complex system of interconnected cogs and wheels, shafts and stays allow the circular roof (and, hence, the sails) to be orientated according to the direction of the wind and so exploit the natural resource to grind the salt (as in this case) or to pump water (if the windmill is situated between two pans). Should the mill be required to pump water, the gearing is harnessed to an Archimedes’ screw.
The sails can rotate at a speed of 20km per hour and generate a power equivalent to 120 horsepower.
